UNITED f STATES PATENT OFFICEe HEINRICH SIMONS, OF AIX-LA-CHAPELLE,GERMANY.

RESPIRATQR.

SPECIFICATION forming part of Letters Patent No. 531,011, dated December18, 1894.

' Application filed November 7, 1893. Serial No. 490,326. (No model.)

To all whom it may concern:

Be it known that I, HEINRICH SIMoNs, a citizen of the German Empire,residing at Aixla-Chapelle, Germany, have invented certain new anduseful Improvements in Breath-Regulators, of which'thev following is aspecification. i

The object of the instrument which in the accompanying drawings isrepresented about twice its actual size is to serve as a means forregulating the operation of breathing and thereby purifying the bloodand strengthening the lungs.

It consists of a short tube a taperingsomewhat toward its front end,where it is closed by a valve c disposed at the extremity of a spring band of a protector e e adapted to preserve both valve and spring fromdamage, the other end of the device being adapted to serve as amouth-piece.

In the accompanying drawings Figure 1 is a front elevation of. theentire instrument; Fig. 2,aback end view of the same and Fig. 3 a planof it.

The breath-regulator is used in the following manner: The end CZ of theinstrument isplaced in the mouth'and holding it tightly with compressedlips, theused up or impure air contained in the lungs fand loaded withcarbonio acid gas, is blown out through the instrument with such forcethat the valve c is raised and assumes the position indicated in Fig. 1by dotted lines.f In this way the lungs are emptied from the vitiatedair to an extent that cannot be attained i'n the ordinary movement ofeven the strongest expiration,

since, in consequence of the resistance oered by the valve c the airmustbe blown out with more force than ordinarily and consequently beexpelled from the lungs with full strength. As soon as expiratory actionceases, the valve c closes and the air of inspiration .must enter by wayof the nostrils so that it may reach the lungs warmed and vrfree fromdust. The

preceding full and abundant expiration will, have increased the capacityof the lungs for taking up a supply of air larger than that conveyed tothem in ordinary unassisted breathing. Hence a deep inspiration ensues,by which an abundant supply of oxygen is conveyed to the lungs and theresult is a purification ofthe venous blood from carbonio acid and itsconversion into oxygenated arterial blood, whereby a most natural andra'- tional blood purification is established in the body.

The strengthening of the lungs above referred to results in consequenceof the resistance offered by the valve c which is closed by the pressureof the spring, to the air expelled from the lungs, since through theressy peated exercises or gymnastics to which the ve e arranged abovethe valve c and spring b serves to protect the spring and valve fromdamage, inasmuch as the protector in order to be used at any time, isintended to be worn by a cordxor ribbon fastened round the neck andpassed through the eyelet f.

Having thus fully described my invention, what I do claim, and desire tosecure by Letters Patent, is o In an instrument for regulating thebreathing the combination ot` a short tube such as t tapering somewhattoward its front end, the other end being ladapted to be receivedbetween the lips, the valve c closing its front tapered end, such valvebeing disposed at the extremity of a spring b fixed to the tube a andthe protector composed of two crossbridges e e substantially as setforth and for the purpose stated.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

HEINRICH SIMONS.
